The FANUC A20B-2902-0674 is a module printed circuit board used inside selected FANUC βiSVSP combined servo and spindle amplifier units. It works with the amplifier’s power and control PCBs and is not a complete servo drive or a general CNC main board.
FANUC maintenance documentation lists this module for specific 18-class βiSVSP two-axis and three-axis configurations. Compatibility must be checked using the complete A06B amplifier order number, unit specification and the other installed PCB numbers.

βiSVSP Servo and Spindle Module Function
A20B-2902-0674 forms part of the internal electronics of a combined βiSVSP amplifier. It operates with the unit’s control PCB and power circuitry to support the configured servo-axis and spindle sections. Because it is an internal module, it cannot be commissioned or tested as a standalone CNC board.
Documented Amplifier Compatibility
Documented applications include A06B-6164-H224#H580, A06B-6164-H244#H580, A06B-6164-H344#H580 and A06B-6164-H364#H580 configurations. This does not mean every A06B-6164 amplifier uses the same module. Confirm the full amplifier nameplate, A06B-6164-C unit number, A20B-2902-0674 board label, hardware revision, connector layout and associated control PCB before ordering.
Testing and Installation Notes
REACO CNC checks the board label, connectors, ICs, solder condition, unit recognition, startup status and applicable servo/spindle operation before shipment. Back up CNC, servo and spindle parameters before replacement. Qualified personnel must isolate incoming power and wait for the DC link to discharge before removing the amplifier cover or PCB.
